中文摘要:

Eichenbaum 和同事观察到一样的地方确实激活在取决于地方是否是为老鼠到的方法的马头鱼尾的怪兽的房间接近的“目标途径”特定的目标。有这的平行,现在的 neuroimage 学习揭示了那,当它与这项任务有关在手边比时,项目的一样的类型能更激活马头鱼尾的怪兽什么时候它不。当他们在在词对包含的关系的类型上做了判断时,参加者被 fMRI 扫描(例如,词对,“家具桌子”,包含一位“范畴模范”关系 ?) 。事件相关的分析表明形成“任务相关”的协会多于的激活马头鱼尾的怪兽“任务无关”就算它是项目的一样的类型,这海马趾的差别没被不同判断,也不由“是”的效果引起要求反应。一致地,判断以后的暗示召回测试比为一样的类型为“任务相关”的协会展出了更好的检索表演但是“任务无关”的协会。结果也显示出那,在 to-be-associated 个人词之间的语义相关海角(例如,相关的词对“健康医院”对无关的词对“价格方法”) 当它是“任务无关”的时,不是足够激活马头鱼尾的怪兽。通常,我们建议通过参予“任务相关”的协会形成并且阵发性的存储器巩固,马头鱼尾的怪兽使有机体能保留为未来用法在头脑拥有了大幸存值的信息。

英文摘要:

Eichenbaum and colleagues observed that the same place did or did not activate the "goal-approach" cells in hippocampus depending on whether the place was the way for rats to approach specific goal. Parallel with this, the present neuroimage study revealed that, the same type of items could activate the hippocampus more when it was related to the task at hand than when it not. Participants were scanned by fMRI while they made judgments on the type of relationships contained in the word-pairs (e.g., Does the word pair, "furniture-table", contain a "category-exemplar" relationship?). Event-related analysis revealed that the forming of "task-related" association activated hippocampus more than that of "task-unrelated", even if it was the same type of items, and, this hippocampal difference was not caused by the different judgment requirements, nor by the effects of "yes" response. Consistently, the post-judgment cued-recall test exhibited a better retrieval performance for "task-related" associations than for the same type but "task-unrelated" associations. Results also showed that, the semantic relatedness between the to-be-associated individual words (e.g., the related word pair "healthy-hospital" versus the unrelated word pair "price-way") was not enough to activate the hippocampus when it was "task-unrelated". Generally, we proposed that, through participating in forming of "task-related" associations and consolidating of episodic memory, hippocampus enabled the organism to keep the information that owned great survival values in mind for future usage.
